Negative Ion – Tokyo's Health Craze

Appliance giants like Hitachi, National, and Sharp are joining the health salons in touting negative ions as the latest, greatest natural remedy to treat everything from allergies to seasonal affective disorder. 

All clinical evidence of pain relief, stress relief, and anti-depressant effects comes from inhaling air that has been purified by negative ions.

National's negative-ion washing machine (¥128,000) promises fluffier clothes, Sharp's fridges claim to keep food fresh longer, and Hitachi's ion-care range includes hair dryers, curlers, and styling brushes to blast particles at you while you groom.
